Captain prien's submarine was the first to reach the bay of daskappa. As early as the early morning, he crossed the waterway and reached here to hide.
At that time, if he wanted to attack, he could choose all the warships in the harbor. Of course, he would first put his target on the Royal ark aircraft carrier.
Or, other aircraft carriers, as well as battleships, pick up a big pick. If you launch four torpedoes at a time, you can't believe you can't kill each other.
However, he did not move. If he moved at that time, he would disturb the British people here and make them raise their alert. The air raid this morning could not be carried out.
According to the plan, as long as our bombers start dropping bombs, u-47 submarine can move.
In fact, he did the same. He sat under the water and remained silent. In the morning, when he heard the first explosion on the water, the officers and soldiers in the whole submarine immediately took action.
Start the engine and float up to periscope depth! The sailors prepared quickly.
The submarine of more than 800 tons, with its huge body, is slowly floating up. The two AEG Gu 460 / 8-276 electric motors at the tail break out the maximum horsepower of 750 horsepower. The propeller at the tail soon reached the maximum speed of 296 revolutions per minute.
At this time, there is no need to worry about the other party's anti submarine system. After all, the other party has been bombed, and it is too late to deal with the bombers overhead. How can it manage the underwater situation? One after another explosion will cover the sound of the submarine.
Now, they must act quickly, occupy their seats and prepare for attack!
In the bow torpedo cabin, the sailors are ready and only wait for the fierce attack to begin!
Operating a submarine is not as easy as driving. Although they have operated at the most skilled speed, it took about three minutes to level it at a depth of 10 meters underwater. Then, on the submarine bridge, the periscope stretched out.
Just as the periscope stretched out, a thicker pipe was slowly rising on the side of the submarine's bridge.
This tube is much thicker than the periscope. When it is not in use, it is vertically and horizontally placed on the submarine shell.
Now, the side hydraulic device makes the thick pipe stand upright, the root rotates, and the automatic locking pin fixes the pipe at the back of the command console enclosure.
The use of periscope on submarines has a long history. It can be said that since submarines entered the naval sequence, periscope, an optical device, began to be equipped.
However, this thicker pipe is now confidential. For submarines, it is an equipment that greatly increases the combat capability of submarines. Its scientific name is submarine vent pipe.
Submarines use diesel engines to sail on the water and charge their own batteries at the same time. However, underwater, they can only use batteries.
Battery power is precious. For example, if you sail at the highest speed, you can't last an hour.
Therefore, submarines in this era spend most of their time sailing on the water. They only dive underwater when they need to attack.
However, surface navigation is very dangerous. The ubiquitous anti submarine aircraft is the biggest threat to submarines. In this way, it is very urgent to let submarines navigate underwater and use diesel engines.
This device is the vent pipe.
The reason why the diesel engine can't sail underwater is that the diesel engine needs to inhale air and exhaust gas. Now, this pipe is used for this work.
The inside of this pipe is divided into two parts, half inlet and half exhaust.
As long as the pipe can go outside, it can exchange air with the outside world. In this way, although the submarine has not surfaced, it can start the diesel engine at the tail!
For the captain of a submarine, it is his most hope to keep his battery fully powered at all times. At that time, he is most confident.
Because only a small vent pipe is exposed, it is difficult to be found by surface ships.
There is a floating mechanism on the top of the intake pipe, which is very similar to the floating ball in the toilet.
When the mast is in the water, the floating mechanism will automatically close and block the air inlet pipe, so that the external seawater will not enter the submarine through the air inlet pipe. When the mast is exposed to the water, the floating mechanism can be opened by itself to connect the air inlet pipe with the outside world.
Now, with the continuous rotation of the pipe, soon, when it turns to the vertical state, the top has been exposed, the vent pipe opens automatically, and the seawater remaining in the air inlet pipe flows into the auxiliary ballast tank on the boat.
"Start the diesel engine," Captain prien shouted, staring his eyes at the periscope in front. It was almost synchronous. After the vent pipe went out, the periscope also went out.
In the back, two 1400 HP diesel engines of man company made a deep sound, which was quite familiar to the submarine soldiers.
After the diesel engine is started, the exhaust pressure blows out the sea water in the exhaust pipe. Light blue smoke appeared on the sea.
In history, Germany only experimented with this device in 43 years and installed it on submarines produced in 44 years. In fact, this technology appeared very early.
For example, as early as 1938, the Dutch Navy conducted a series of tests. Submarines sailing in periscope depth realized underwater diesel propulsion by using a single pipe ventilation system, which gave submarines almost unlimited underwater range in theory.
Unfortunately, the German Navy did not notice the importance of this invention at the beginning. In their eyes, this device is only a means for the submarine to circulate air.
Now, the technology of this vent pipe was put forward by hilrick at a naval equipment meeting. After development by experts, it has matured and become a killer mace of the German Navy submarine force.
The diesel engine at the tail rumbled, while the atmosphere in front was very tense. For the submarine soldiers, their attack was about to begin.
After lifting the periscope, Captain prien immediately began to observe the sea. At this time, warships were on fire, smoke billowed everywhere, and almost no valuable target could be seen on the sea.
Leave me something! Captain prien was extremely depressed.
After a turn, Captain prien was still happy: "the left rudder is full, ready to attack!"
On the sea, there is still a big guy several kilometers away from the port. Although prien can't identify the specific model and ship name of the other party due to the angle problem, it is definitely a large battleship!
The warship is smoking black smoke, but it hasn't sunk yet. Just let yourself send it to hell!
Left full rudder! The tail of the submarine stirred the water. It belongs to the hunting of u-47 submarine. No, the slaughter officially began!
Please report us if you find any errors so we can fix it asap!
